Rapid and accurate differentiation of spp. causing enteric fever from nontyphoidal is essential for clinical management of cases, laboratory risk management, and implementation of public health measures. Current methods used for confirmation of identification, including biochemistry and serotyping as well as whole-genome sequencing analyses, take several days. Here we report the development and evaluation of a real-time PCR assay that can be performed directly on crude DNA extracts from bacterial colonies for the rapid identification of typhoidal and nontyphoidal .

Hazardous effects of heavy metal pollution on Nile tilapia in the aquatic ecosystem of the Eastern Delta in Egypt.
BMC Vet Res
December 2024
Department of Zoology, Faculty of Science, Benha University, Benha, 13518, Egypt.
Introduction: Heavy metal pollution threatens the biodiversity and ecological equilibrium of the Nile River. This study investigates the impact of heavy metal pollution on aquatic animals such as Nile tilapia (Oreochromis niloticus) in the Damietta branch of the River Nile and El-Rayah El-Tawfeeky canal in Benha City in Egypt.
Methods: Fish and water samples were collected from the Damietta branch and El-Rayah El-Tawfeeky during the fall of 2022.
MicroRNA-668 alleviates renal fibrosis through PPARα/PGC-1α pathway.

Department of Nephrology, The Third Xiangya Hospital, Central South University, Changsha, China.
Background: The involvement of microRNA-668 (miR-668) in the onset and progression of renal fibrosis remains unclear. To this end, we aimed to explore the relevant mechanism of miR-668 in renal fibrosis.
Methods: C57BL/6 J male mice were randomly divided into sham-operated, unilateral ureteral obstruction (UUO), and UUO-fenofibrate groups.
The transcription factor YbdO attenuates the pathogenicity of avian pathogenic Escherichia coli by regulating oxidative stress response.

Avian pathogenic Escherichia coli (APEC) is a significant pathogen infecting poultry that is responsible for high mortality, morbidity and severe economic losses to the poultry industry globally, posing a substantial risk to the health of poultry. APEC encounters reactive oxygen species (ROS) during the infection process and thus has evolved antioxidant defense mechanisms to protect against oxidative damage. The imbalance of ROS production and antioxidant defenses is known as oxidative stress, which results in oxidative damage to proteins, lipids and DNA, and even bacterial cell death.

Center for Biomedical Engineering, School of Engineering, Brown University, Providence, RI 02912, USA. Electronic address:
Automated liquid handlers are fundamental in modern life science laboratories, yet their high costs and large footprints often limit accessibility for smaller labs. This study presents an innovative approach to decentralizing a liquid handling system by converting a low-cost 3D printer into a customizable and accurate liquid handler. The Personal Automated Liquid Handler (PALH) system, costing ∼$400, incorporates a single-channel pipet, custom 3D-printed components, and open-source software for personalized workflows, allowing researchers to build and modify the system for specific experimental needs.

Objective: Septic acute lung injury (ALI) is a common complication of sepsis with high morbidity and mortality but lacks specific treatment. This study aimed to elucidate the role of circular RNA TLK1 (circTLK1) in neonatal septic ALI.
Study Design: Murine cecal slurry was used to induce neonatal sepsis-induced ALI model in vivo.
